1 Grist Management Key Considerations of Flour Production: AGIC Conference 30 th July, 2013 John Bunn, Milling Consultant. JB Milling
2 Bunge (Aust.) - 17 ½ years Ballarat Narrandera Ballarat Australian Wheat Board 20 ½ years Baghdad Cairo H.O. (Melbourne) Serendib Flour Mills 2 years Colombo, Sri Lanka. Chief Technical Officer Consultant Flour Miller since 2009
3 South East Asia Indonesia new Mills Middle East upgrading of older mills East Coast Africa Old milling companies expanding into neighbouring countries Some have literally built their business on Australian Wheat
4 Wheat procurement costs are at least 70% of the manufacturing costs for a Mill. Competition strong. Millers looking for an edge to gain any extra sales.
5 1. Price Wider Range for procurement Eastern Europe Other wheat sources Freight
6 2. Suitability to End Product a) Special attributes b) Bread wheat for Bread biscuit wheat for biscuits
7 3. Protein (Wet Gluten) a) Expensive b) Important Parameter - Quantity & Quality c) Miller s customers work on WG d) Eastern European dilemma Russian Wheat Bug
8 4. Impurity Level a) No flour from Impurities b) 100 5% = 95 tonnes Millable Wheat
9 Impurities Wheat A Wheat B Parcel (Tonnes) Impurity Level (%) 2 5 Millable Wheat 98 95
10 4. Impurity Level a) No flour from Impurities b) 100 5% = 95 tonnes Millable Wheat c) More impurities less Millable wheat available d) Cleaning equipment impurity type - Impurity percentage a) Freight Issue
11 5. Moisture Content a) An immediate impact on profit.
12 Moisture Wheat A Wheat B Parcel (Tonnes) Moisture Level (%) Water Addition to 15% (Tonnes) Millable Wheat
13 5. Moisture Content a) An immediate injection of profit b) High protein wheat actually require extra water during the Conditioning process c) Freight factor
14 6. Flour Extraction Potential a) An immediate injection of profit
15 Potential Flour Extraction Wheat A Wheat B Parcel (Tonnes) Flour Extraction (%) Flour Produced (T) 78 75
16 6. Flour Extraction Potential a) Higher flour Extraction equals Higher Profit (but not always) b) Different varieties and Grades have different Flour Extractions c) White wheat has higher Extraction than Red Wheat d) The same variety grown in different growing regions have different Flour Extraction rates.
17 Impurities, Moisture and Extraction Wheat A Wheat B Parcel (Tonnes) Impurity Level (%) 2 5 Clean Wheat (T) Wheat Moist (%) Millable Wheat (T) Milling Extraction (%) Flour Produced (T) ,000 tonnes( T) 41,250 36,900 4,350 Tonnes
18 7. Reliability & Consistency a) Automated machinery. b) High tonnage throughput. c) Miller and his customer need consistency of product.
19 8. Hygiene a) Contaminated wheat b) Flour Mills going through a process of ensuring their mills minimise contamination. c) Mill and equipment design minimising dead pockets.
20 The Grading System The Grading System has been the mainstay of Australian wheat quality As such millers around the world have come to rely upon it Provides millers with predictable flour quality Therefore, everything must be done to retain the reputation of Australian wheat Quality
